IMPROVEMENT IN CLOTH-MAPPING MACHINES.

Specification forming part of Letters Patent No. 153,660, dated August 4, 1874 application filed May 29, 1874.

the following is a ful],clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is an end view of my improved gig, showing the skeleton cylinder to which the flats which carry the teasels are attached, the frame which supports one end of said cylinder, the frame which carries the clothbeams, the clutches for connecting them to the driving-gearing, the driving-pulley, and the revolving brush for cleaning the teasels, with the pulleys for driving the same, and the lever for placing the brush in position and motion. Fig. 2 is a view of the opposite end of the machine, showing the frame-work, the revolving cylinder, the gearing and lever for reversing the movements of the cloth-beams and the revolving brush. Fig. 3 is an elevation of the rear side of the machine,'showing the position of some of the parts above enumerated, together with the shaft and arms which carry the revolving brush, the laterally moving andreversible frame which carries the cloth-beams, and the hand-wheel for operating the same; and-Fig. 4 is a plan View, showing the skeleton cylinder, the frame-work, the driving pulleys, the upper cloth-beam, the

frame which carries it, the stud upon which,

said frame rotates, the method of connecting the beams to the driving-gearing, the handwheel for giving lateral movement to the frame, and the flat which carries the teasels,

and the method of attaching it to the cylinder.

Corresponding letters denote like parts in all of the figures.

This invention relates to that class of machines which are denominated gigs, and which are used for raising a nap upon cloths during the process of finishing such goods While in the Web; and it consists in certain improvements in such machines, as will be more fully set forth hereinafter.

In constructing machines of this character, I use a frame, A A, of iron, or any other suitable material, it being constructed substantially as shown, or so as to receive and support the other parts of the device. Between the vertical portions A A of this frame there is placed arevolving skeleton cylinder, B, the journals of its shaft resting in boxes, or other bearings attached thereto in such a manner that it may rotate freely, it being driven by a pulley, B, upon the outer end of its shaft,

. or by gearing placed thereon. Upon the same shaft on which the driving-pulley is placed, and by the side thereof, there is placed another one, which is made to revolve freely on said, shaft, it being designated by the letter and numeral B Upon the inner surface of the last-named pulley there is a projection, B, which is for the purpose of receiving a belt or cord, which passes from it to and under idlers or loose pulleys O G, and from there to and around a pulley, G placed upon the shaft of a revolving brush, which, by referring to the drawing, will be seen as placed below the cylinder B, where it is located for convenience,

but which may be placed in any other loca-' .tion where it can be readily revolved. This brush consists of a cylinder of the required size, its periphery being furnished withprojecting wires, stiff bristles, or any other material which will enable it, as it is rotated, to clean the teasels as they are successively brought in contact with it. i The method of arranging this brush, with reference to the cylinder which carries the teasels, is to extend from one of the end frames A to the other a rod of metal, upon which there are placed two arms, 0 and c, which are firmly secured to the said rod, it having its bearings in the frames A A. Through the outer ends of the arms 0 and c the shaft of the revolving brush D passes, and carries upon its outer end the pulley 0 which is thus brought in line, or nearly so, with the pulley B on the main shaft of the machine.

This arrangement of the revolving brush and its arms, with reference to its pivotal points, provides for its being brought into contact with the teasels while they are in their revolved or turned upon its pivot, and again pushed inward when the pinion upon the handwheel shaft will enter another toothed slot in the plate upon beam F and thus by turning said wheel the clutches upon the opposite ends of the beams will be made to engage with those upon the driving-shafts, and so by again passing the cloth around the teaseling-cylinder and fastening its ends to the empty beam and putting the machine in motion, the desired result will be accomplished.

The method of giving motion to the clothbeams, which I prefer, is the one shown in the drawings, and consists of a pinion placed upon the driving-shaft, which meshes into a spurwheel placed upon a stud, which is secured to the main frame of the machine, and which, in turn, meshes into a pinion attached to and revolving upon a stud on the end of a lever, the pivotal point of which is upon the stud upon which the spur-wheel just referred to turns. This last-named pinion meshes alternatelyinto spur-wheels placed upon short shafts which pass through arms cast upon the end of the main frame, and upon the inner ends of which the clutchcouplings before referred to are placed, which rotate the cloth-beams. The lever referred to extends from its pivotal point outward to some convenient point for opera-- tion, near which it is allowed to engage with a plate of metal or some other device for holding it in position, it being so arranged that when in its central position its pinion will not engage with either of the spur-wheels, which drive the cloth-beams, and will rotate freely between them, but as its outer end is raised or lowered it will mesh with one or the other of the wheels, and thus enable the operator to cause the cloth to be wound from one beam to the other, as he may desire I am aware that a revolving frame for carrying the cloth-beams of a teaseling-machine is not a novel feature, and hence I do not claim such a device broadly; but

Having described my invention, what I do claim, and desire to secure by Letters Patent, 18-- V o 1. In a cloth-napping machine, a reversible cloth-roller frame, substantially as described, which can be moved laterally and rotated when required, as and for thepurpose set forth.

2. In combination with a cloth-napping machine, a revolving brush, D, oscillating arms 0 and O and a lever, D, the parts being arranged to operate substantially as and for the purpose set forth.

3. In combination with the teasel-carrying flats, the metal plates E on the lugs of the cylinder, one bearing upon the side of one of the longitudinal bars of the flat and the other upon the edge of the other bar, as and for thepurpose set forth.

In testimony that I claim the foregoing as my own invention, I have affixed my signature in presence of two witnesses.
